It is suitable for new designs and volume production BOMs.","metaTitle":"DSC1101CI5-157.2864 MEMS XO 157.2864 MHz CMOS ±10 ppm","metaDescription":"Microchip DSC1101CI5-157.2864 MEMS oscillator, 157.2864 MHz CMOS output, ±10 ppm stability, 2.25-3.6 V supply, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"CMOS","Series":"DSC1101","Package":"Tube","Ratings":"-","Function":"Standby (Power Down)","Frequency":"157.2864 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-VDFN","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC1101","Frequency Stability":"±10ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"35mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"95µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the DSC1101CI5-157.2864 compatible with 3.3 V and 2.5 V systems?","answer":"The CMOS output swings rail-to-rail, matching the logic threshold of the downstream device without a level translator."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1101CI5-157.2864","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1101CI5-157.2864 when reusing this data.
